SPECIFICATION forming part of Letters Patent No. 634,470, dated October 10,1899.

Application filed May 10, 1899. Serial No. mam. No model To ctlZ whom it may concern:

Be it known that I, ALBERT MARKS, a citizen of the United States, residing at Spring Lake, in the county of aushara and State of lVisconsin, have invented certain new and useful Improvements in Portable Filtering Devices, of which the following is a specification. 1 My present invention pertains to improvements in portable filtering devices, the construction and advantages of which will be hereinafter set forth, reference being had to the annexed drawings, wherein- Figure 1 is a side elevation of the complete apparatus 5 Fig. 2, a vertical sectional view of the filtering-chamber, and Fig. 3 atop plan view of the same.

In the use of traction-engines and the like.

the question of a suitable water-supply is one which frequently gives no little trouble, for, as is usually the case with such engines, the supply must be drawn from creeks and streams own tank along with them or have the feeda tank mounted on the frame or running-gear of the engine, and in passing up or down an incline when the water is low in the tank the supply-pipe or opening thereto "is frequently;

, uncovered, allowing air to be drawn into the overcome both of these difficulties and to in-- sure a clean-water supply and at the same time a constant one, notwithstanding that the volume of water in the tank below and the apparatus is passing over an uneven country.

Referring to the drawings, A indicates the body of the tank, which in the present instance is shbwn as mounted upon an ordinary vehicle running-gear, said tank or receptacle having an opening B, formed in the bottom thereof, as shown in dotted lines in Fig. 1 and in full lines in Fig. 2. Said opening is preferably formed near the center of the tank, for a purpose that will presently appear. Se-

This also at times cured to the under face of the tank is a filtering-chamber =01 trap G, the location of the chamber being such that the opening B is in communication therewith. This filteringchamber is preferably formed-with a downwardly-inclined face or bottom D, provided at its lowest point'with 'a draw-off which is closed by a plug E. To provide forthe filtra tion of any water which passes through the trap or filtering-chamber O, I employ a screen F, which may be of any suitable substance or material capable of straining the water and yet'at the same time permitting a suffic'ient flow therethrough. The material used may be canvas, finely-woven wire, a medium of baked clay, or the like.

Referring more particularly to Fig. 2, it will be noted that the screen F is placed in an inclined position, so that any water which passes through the same will move in an upward direction.

G denotes the outlet, which in practice is connectedby a suitable hose or pipe to the injector or pump of the engine. This outlet is placed upon the opposite side of the screen F from theopening G, so that any and all of the water which is drawn out through said outlet Gmust of necessity pass through the filtering screen or medium. will be cleansed of those matters which it is desirable to exclude from the working parts of the pump or engine.

By reason of the inclined position of i the filtering screen or medium the dirt which will accumulate on the under side or face thereof will have a tendency to fall to the bottom of the filtering-chamberor trap, and said screen or filtering medium may be readily and easily In so doing it.

to the bottom of the tank the water will at all times or practically so cover said opening and prevent the drawing in of air through the same. Of course when the bottom of the tank is in a horizontal position the'water therein will naturally cover the opening as I long as there is any liquid leftin the tank.-

The invent-ion is susceptible of various modifications in its detail, especially with reference to the formation and construction of the filtering-chamber or trap. So, too, the idea is applicable, as above stated, to tanks or reservoirs which are carried directly upon or by the engine, and the form shown in Fig. 1 is to be taken simply for the purpose of illustration.

By having the filtering-chamber or trap in communication with the tank through a small or restricted opening the water which enters the filtering-chamber or trap will be held therein against displacement by-a inoment-ary tilting of the body of the tank. This isimiportant wherebut a small quantity of water is-heldby thetan'k, and theopening B will be uncovered and air be free to enter therethrough. The restrict-ed opening also prevent-s10 a certain degree themudor other material which will accumulate upon the bottom of the tank from entering the filtering-chamber, except that which .is' directly around it or passes directly over it as the water may move back from one end of the taukto theother.

:Having thusdescribed my-invention, what I claim is '1. In combination with a tank; a filteringchamber or trap secured to the underside thereof; an opentug-extendingfromsaid milk into the filtering-chamber; a filtering medium mounted within said trap, to oneside of the opening; andan outlet in said .trap upon theopposite side of the filtering medium.

2. In combination with a portable tank having an opening in its base; a filtering-chamberin communication with said opening; a filtering medium mounted within said chamber, to one side of the opening in the tank; and an outlet for said filtering-chamber, ar-

ranged upon the opposite side of said filtering medium, substantially as described.

A portable filter comprising a suitable tank or receptacle provided with a dischargeopening formed near the center of its base; a filtering-chamber or trap in communication with said opening; an opening leading from the trap; and a filtering medium interposed between said openings, substantially as described.

4. A portable filter comprising a suitable tank or receptacle having an opening formed centrally in its base; va filtering-chamber or trap secured to said tank and in communication with the opening, said chamber being formed with an inclined face or bottom D; a draw-oft opening formed at the lowerend-of said inclined face; an outlet-G; and a filtering medium extending across the filtering- .chamber or trap, intermediate the openingG and the central opening in the base 'of the tank.

5. In a portable filter, the combination of a suitable tank or receptacle provided with a central opening in its base; a filtering-chamanouttlet for the filtered water leading from the trap.

In witness whereof I hereunto set my hand in the presence of two witnesses.
